Abstract:  The death of George Floyd has triggered the resurgence of discussion on racism. Yet we should not simply interpret this incident  as a racial issue, but simultaneously examine the resulted Black Lives Matter（BLM）movement in a holistic manner. Different from traditional civil rights movement in the past, the BLM movement is fundamentally a kind of identity politics led by “intersectionality”.In response to people’s challenge to the narrow group consciousness of identity politics, black feminists proposed the theory of intersectionality to integrate multiple identities to strengthen resistance.However, intersectionality has also encountered many problems in praxis. Because it fails to transcend identity politics’ mistake in disregarding economic issues, it remains essentially a reformist plan of capitalism,unable to effectively aggregate forces against capitalism. This enlightens us that new social changes should return to  the perspective of Marxist theory in the pursuit of eliminating the capitalist system.
